Risk of Very Scary Black Holes
Black hole capable of swallowing a variety of celestial bodies. The more he swallowed, the greater its appeal. But the risk is not only that.
Black hole is a region of space that can swallow gas, dust, stars, planets, and other celestial objects that exist in a galaxy. Its gravitational pull is very strong. A planet passing in the vicinity will not survive the suction hole.

Many astronomers worry that the more illegal activities will be able to swallow the Earth. So what makes a black hole can suck objects around space?
There is actually a theory which states, the suction power of a black hole can be weakened and then he would go into a phase of sleep, stop eating celestial body. According to George Helou, from NASA's Spitzer Science Center at the California Institute of Technology, a black hole in our galaxy is currently in a phase of sleep.
Black hole called Sagittarius A is located in the center of the Milky Way galaxy. Scherbakov, astronomers from the Harvard Center for Astrophysics said the black hole at the Milky Way takes only 0.01% of stars around him.
But now researchers also discovered a fact, black holes constantly evolving, so that they can be active again someday. The more he swallowed a star, the sooner the process of evolution.
According to data obtained from space telescopes, over the last few years, a growing number of black holes swallowing celestial body. In addition, it is said that the more he sucked celestial body, the greater its appeal. This is because an increase in ionic elements in it.
But not only evolved, later also known black holes that exist in different galaxies are also joined to each other. Various celestial body that goes into the black hole contains a lot of energy in large quantities.
So that the joint between the black hole would also increases the amount of energy it has. This energy can control the flow in and out of gas and dust out of the hole.
Not only the dust and gas, astronomers believe that a black hole sucking too much release of X-rays and radioactive waves. But the number of X-ray radiation they observe can not be explained. What is clear, everything that affects the development of the galaxy where the black hole is located.
Understanding the process, the workings and evolution of black holes is important to explain the formation of the Milky Way and the integrity of the earth in the future. Studying the interaction of intergalactic radiation and can make us understand the magnitude of the gravitational field, magnetic force, and the black hole radiation.
"We have been studying data from space telescope over the last few years, and found that the faster the black hole devouring material space, the higher the ionization power," says David Ballantyne, assistant professor of physics Georgia Institute of Technology.
Space physicists do not currently have an adequate explanation of the suction power of black holes and how to grow or what makes a particular black hole stops growing. But clearly, the black hole and the disc will affect the surrounding sky objects.
"Sucking on a celestial black hole releases a lot of energy. Not only radiation but also the gases released until far into the outer galaxy. This gas can change the order of the location of stars, and stop the development of galaxies, "Ballantyne said.
"Power continues to suck black holes studied. There is a growing and some are dead. Studying is important to know the shape and change the composition of our galaxy, "Ballantyne added.
Black hole is sucking celestial body. Earth at risk of being swallowed by it. But the risk was not only that. The gas ejected from the inside can make a celestial body to shift, and may even crash.
